Traditional Caddo Potter

Although I originally set out to find an art form that I was comfortable with and would be inspired by, for myself, I ended up discovering an ancient art form that would benefit not just myself, but the generations of Caddo people that would come after me. I feel that eventually they will see the benefit from its rediscovery. But also, I quickly realized the need to make public the distinction of our ancient pottery legacy for the sake of those Caddo that would pick up the craft. The Native American art world in the American Southeast is much different from that of the Southwest that I grew up loving. So many Native American artists are confused about what is their tribe’s specific legacy and traditional art form that many claim a broad spectrum of tribes in the region by creating artwork under the umbrella of “Mississippian” or “Southeastern Ceremonial.” It became apparent that the Caddo’s specific and unique pottery heritage is in danger of being misrepresented in the art world and to collectors. Making it all the more obvious was that I found out there was only one active Caddo member practicing pottery making, Jereldine Redcorn. I felt like although she was successful in reviving the lost art of our Caddo pottery, there is only so much one person can do and it was then that I decided that I could help expand and help spread our knowledge and our experiences so that our beautiful pottery tradition could be reborn and survive for all time, rather than become lost again in the earth

A compilation of digitized satellite imagery of the Gulf Stream (1982, 1983, and 1985)

Ninety plots of digitized temperature boundaries from infared satellite images of the Gulf Stream along with corresponding image snapshots were compiled to determine stream width propagation speed. The satellite images are from the years 1982, 1983, and 1985 and are often of consecutive days. In this report, these images and digitized plots are presented.Funding was provided by the Office of Naval Research through contract Number N00014-87-K-0007, and by the National Science Foundation under grant Numbers OCE 87-00601 and OCE 85-10828

Impurity complexes and conductivity of Ga-doped ZnO

Using hybrid functional theory together with experimental measurements, we investigate the influence of gallium impurities and their complexes on electrical properties of ZnO. In contrast to the behavior of isolated Ga impurities and native defects, the calculated formation energies of Ga complexes are consistent with our experimental data. We show that for high levels of Ga doping the acceptor behavior of GaZn-VZn and GaZn-Oi complexes explains the conductivity measurements and compensation levels in ZnO. The computed binding energies of these complexes are also consistent with the binding energies obtained from the measurements of the temperature dependence of carrier mobility. Our results show that the formation of defect complexes, often overlooked by theory, can be indispensable in capturing the defect physics

Little Pomerania and Other Stories

The stories in this thesis represent a portion of the work I have done during my time as a student in the creative writing program at the University of Maryland. They were ultimately chosen for their thematic links and because they--I feel--best represent the writer I have become over the last three years. Collectively, the stories deal with class, communication, culture, disappointment, displacement, marriage, and maturity, sometimes all in the same story. While each story is meant to stand alone, it is arranged here in a deliberate order, relative to the others, as there is a discernible arc
